Yes, it is a fast wheel, but its hard for someone running the scene to see much happening or determine the speed. You could set the hinge torque to max, toggle the brake with the enter key, and display the angular velocity on a plot. That way the user can see how fast the wheel accelerates and that the top speed is 157 rad/sec (approximately 1500 RPM).

The wheel does not always go in the same direction. There may be some way to make it always start in the same direction. That may be difficult.

You should give credit to "awesome person" for his scene which demonstrates the same effect. Another approach would be to make your scene a response to "awesome person's".
